Trace 1 in Figure 3 depicts the start-up of a 2.4-kW power supply with the inrush-current limiter and a slow-start circuit, which allows the separation of the inrush and the start-up processes. The ...

The simple current-limiting load switch shown in Figure 1 will be familiar to most readers. In this circuit, a high level signal applied to the input switches on MOSFET Q2, which energizes the load.

The current limiting circuit, though, is where things get interesting. Rather than use an op-amp, [DiodeGoneWild] chose a simple discrete transistor current-sense circuit.

Shown is a simple bidirectional current limiter. Figure 4 compares SiC JFETs with other technologies, using the channel resistance per unit of chip area as the figure of merit.

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can ...

This paper proposes an analysis of the inrush load current and a design of the inrush current limiter circuit for a low-voltage DC (LVDC) distribution system. Due to the absence of a zero-crossing ...
